If you were going to replace your 3/S..

[IPD]

depends on which SL AMG we're talking about. SLK's only have 1 variant. At the end of the day though, I'd rather have an SLK AMG than a garden-variety SL.

p.s.
a lot of the benz lovers really like the r171 front over the r172, but they prefer the r172 tail over the r171. and the r170 actually looks good with blacked-out badging & blacked out wheels/tails/headlights. i think that same treatment would fix a lot of my gripe with the r172 looks.

p.p.s.
if i'm reading my numbers right, the 493 ponies (v12 turbo) is the r230 SL600. the SL 55 AMG had 469 (supercharged 8). the SL 65 AMG is 604hp (v12 turbo).
